Loch Lomond Stadial Flashcards
What was the Loch Lomond Stadial?
The Loch Lomond Stadial was a cold period during the late Devensian glaciation characterized by glacial advances and the formation of extensive ice sheets in Scotland and parts of northern England.
When did the ice sheets begin retreating, and when did deglaciation occur?
The ice sheets began retreating 18,000 years ago, and deglaciation occurred 15,000 years ago.
When did a sharp plunge in temperatures occur, and by how much did temperatures drop?
A sharp plunge in temperatures occurred 12,500 years ago, with a drop of 6-7 degrees Celsius.
What significant temperature change occurred in Greenland over a span of 50 years?
Greenland experienced a temperature change of +7 degrees Celsius within 50 years.
What might have triggered the sharp temperature changes during this period?
The draining of Lake Agassiz possibly disrupted thermohaline circulation, cutting off heat from the Gulf Stream, which could have triggered the temperature changes.
